I bought my CTS tires and had them installed at 103,000 miles. They've been nothing but a headache. I've been back to the retailer 3 times with vibration issues. They have checked the alignment of the truck twice, which resulted in nothing. I was informed on my first visit back to the retailer that one of the tires was defective, which they replaced, but it only partially fixed the problem, which is why I have been back. Long story short, after thinking that perhaps something was mechanically wrong with my truck,I replaced wheel bearings, rotors, had an alignment outside of the tire retailer and replaced the tie rods. I finally had enough. I replaced the Cooper tires with Goodyear Wranglers. Truck is as smooth as ever! I have the Cooper tires if anyone is interested, they have about 35% tread left at only 30,000 miles of use with regular rotation. Good riddance!
Worst tire I ever had, they are still over 50% remaining on them and I cant wait until I get a new set on. Just spit on the ground and you're sliding. I wont let anyone else drive it. They are at best good for dry roads.
